To all whom it may concern;

Be it known that we, JAMES P. CONWAY and GEORGE HOFFMAN, citizens of the United States of America, residing at Arnold City, in the county of Fayette and State of Pennsylvania, have invented certain new and useful Improvements in Hangers for Electric Conductors, of which the following is a specification, reference being had therein to the accompanying drawing.

, -and quickly'removed when desired.

With the above and other objects in view which will more fully appear as the description proceeds, the invention consists of the novel construction, combination and arrangement of parts hereinafter more fully described and then specifically claimed.

In the drawing :F igure 1 is'a view in side elevation of a hanger constructed in accordance with our invention, Fig. 2 is a central vertical sectional view of the same,

Fig. 3 is a View in side elevation with the' parts detached, Fig. 4 is a central vertical I sectional view, partly broken away, showing a modified form. of construction, and Fig. 5 is a horizontal sectional view of the spike member of the hanger.

To put our invention into practice, we provide an interiorly threaded body or cup member 6 from the closed end of which eX- tends a spike 7, which may be of any desired cross sectional contour, though preferably it is made in the rib form herein shown, since such irregular contour of the spike enables a better grip being obtained in the material into which the spike is forced.

The body or cup member in the construc tion shown in Figs. 1 to 3 receives "an exteriorly threaded plug 8, which in this instance, is formed of any suitable insulation. In the plug 8 is fixedly secured in any desired manner the shank 9 of a threaded stem or bolt 10, provided with a kerf orslot 10' wardly throughout the length of the threaded portion of said bolt.

In theconstruction shown in F i 4, the cup member 6 and s ike 7 are-identical with that above described: but the plug 8 in this construction is made of metal and provided with a central cavity 11, in which is insulation 12 which carries the stem'l t of the bolt 10. The stem 14. of the bolt in this instance is preferably threaded so as to be firmly held in the insulation 12. The threaded portion of the bolt in this construction is slotted in the same manner as the bolt shown in Figs. 1, to 3.

In both constructions, the slot 10' receives the shank 15 of a supporting hook 16, the free end of the shank 15 being provided with a T-shaped head 17. The shank of the supporting hook is adapted to slide freely in the slot 10 the hook being supported by a nut 18 threaded on the bolt 10 and on which the head of the hook rests. The lower end of the bolt 10 is provided with a transverse groove 19, adapted to receive an electric conductor 19.

With the parts assembled as shown in Figs. 1 and 2, the electric conductor 19 is placed on the bill of the hook member as shown, and the nut 18 is then screwed upwardly so as to bind the electric conductor between the bill of the hook memher and the lower end of the bolt 10 securing the electric conductor firmly in position. Obviously, the loosening of the nut 18 allows the hook member to move away from the bolt so that the electric conductor can be easily removed.

- From the foregoing it will be observed that we have devised a simple and inexpensive hanger wherein the use of tie-wires is dispensed with. We not only save the cost of tie-wires, but the time and labor heretofore required to place the wires in position.

We reserve the right to press or other-' wise mount the insulation'upon the slotted bolt, and while We have herein shown and described a specific embodiment of the invention as it has beenpracticed by us, it will be evident that various changes may be made in the details of construction without departing from the spirit of the invention.

Having fully described our invention, what we claim as newand desire to secure :by Letters Patent, is 1. A. hanger jfor conductor wires, compraisin an interiorly threaded cup member provi ed on its closed end with a spike, a

plug threaded into said on member, a slot-- ted bolt carried by said ug, a supporting hook mounted in said got and ha a head on its inner end, and a nut on the It upon whicl said head rests.

2. A hanger forconductor wires, coin rising a cup member provided on its cl end with a spike, a supporting bolt detachably secured to the cup member and being slotted in the portion projecting beyond the cup member, a supporting hook slidable in the slot of said bolt, and a nut on the bolt for supporting said hook and for moving the same toward the inner end of the bolt.

3. A hanger for conductor wires comprising a cup member provided on the closed end thereof with securmg means, a lug threaded into'said cup member, a ho t carried by said plug and having a slotted outer end, a supporting hook mounted to slide in the slotted portion of the bolt, and means on the for retaining the supporting hook in (positlon and for moving the same toward an away from the cup member.

. 4. A hanger for electric conductors comprising a cup member interiorl threaded and provided on the closed end with a securing spike, a bolt supportedfrom the cu member and insulated therefrom, said t provided with a slotted outer rtion, a supporting hookmovable in the 3 0t of said bolt, and a nut on the bolt supporting said hook and also constituting means to move the hook longitudinally of the bolt.

In testimony whereof we aflix our signatures in the presence of two witnesses.
